Four harpooners compete to land a high-priced monster bluefin tuna. Niko must prove he can run a legendary boat while Joe hunts to support his family.

Captains Joe and Tyler hit bluefin gold. Feeling pressure to live up to his famous father's legacy, strongman Niko changes tactics.

Captain Joe takes his sons to sea aboard the Redrum, only to witness nature at its rawest; Niko hunts the season's biggest bluefin yet, worth $10,000.

As Joe fights to keep his lead, all bets are off when a legend joins the derby. Emmett struggles without a plane until his dad harpoons a giant.

At the mid-season peak, three centuries-old fishing strategies are put to test. Joe relies on instinct, Tyler turns to science, and Niko relies on tradition.

Battling with Tyler for the lead, Joe partners with Niko. But when Niko's zapper fails at the worst possible moment, Tyler steps in to save the day.
